>> months after the tazreen fire, the memories of that disaster - and the ones that followed - are still fresh in people's minds. kalpona akter, a worker's rights activist, rushed to the scene not long after the fire began. >> it was horrific. for my experience, i think, i was crying and still you could feel the heat inside and my skin was burning. it took walmart two days to acknowledge its connection to tazreen... after photographs emerged showing its labels in the wreckage. the walmart clothes wasn't burned to ash, some others maybe, but not them. >> kalpona, like the women who survived the fire, is still haunted by what she saw that day. it's a feeling that when you are on the inside of the building you can feel that how these workers fought to remove these window bars.
